Program för att simulera CD-växlare till en Volvo-bilstereo, anpassat för 16F877A men jag har 16F628A som borde räcka.

Programmet tar någonstans runt 1,5kB så där är det inga problem, tror inte att den tuggar för mycket RAM heller... verkar inte vara mer än vad 16F877A har iaf.

16F628:

Något uppenbart är att debug-pinnen måste flyttas/ändras/tas bort, annars är det kanske bara skillnader i hur man ska ställa in allt?

Jag är inte så hemma på PIC-assembler, så om man kunde få lite hjälp med vad som behövs ändras så skulle det vara tacksamt.

Någon som kan förbarma sig?

Du behöver källkoden. Eller skriva om allt från början.
Eller lägga ner en massa tid på tolknig av din dis-assembly lista.

Jo, det hade förstås underlättat men författaren till koden har inte kvar originalkällkoden till denna version och ägnar sig numera åt nyare versioner av bilstereo.

Det finns en listning av en tidigare version som kanske kan vara till nytta, frågan var väl mest om det fanns något som inte funkar i en 16F628A i den applikation som den används för. Vad jag vet just nu är det bara användandet av port D som ska plockas bort eller flyttas - någon blinkande diod med för mig okänd debug information.

Tanken var väl om någon är van vid PIC-assembler kunde kika om det hittas på något som inte passar för PIC:en med mindre minne osv. Kanske valdes 16F877A bara för att den har programmering via SPI?

Olikheter mellan 16F628A och {16F877A}:
Program Memory (KB) 3.5 {14}
RAM Bytes 224 {368}
Data EEPROM (bytes) 128 {256}
Digital Communication Peripherals 1-A/E/USART {1-A/E/USART, 1-MSSP(SPI/I2C)}

Men det kanske är bättre att fråga på något PIC-orienterat forum istället.

Sen kanske det duger med denna version 0.1 om man bara vill kunna spela upp ljud, om den fungerar som den ska.

Fast jag testar väl att modifiera assemblerkoden för 2.0 och ser om den går igenom...

Nej, det hela använder så pass få pinnar så en 682A ska inte vara något problem.

> Kanske valdes 16F877A bara för att den har programmering via SPI?

SPI ? Menar du ICSP ?

Prova och bygg koden så får den en första hint om
hur mycket som skiljer.

Får man fråga varför du vill gå igenom allt krångel istället för att bara skaffa en PIC16F877A ?

F.ö skulle jag vara EXTREMT intresserad av motsvarande sak för SAAB (9-5)

Jag har inte kollat hur mycket plats det finns över, tänkte att det kunde vara smidigt att fästa den på bilstereons baksida. 40 pinnars PIC:en känns lite otymplig, sen har jag 16F628 hemma och är allmänt otålig.

Jag har ett PicBasic Pro program också, som är utvecklad för en Alpine bilstereo (ska vara samma som för Volvos) med tillhörande kommunikation med hemmagjord mp3-spelare, kontrollkoderna är i princip samma denna versionen verkar kunna skicka lite varierande data, på det hela taget så verkar denna versionen bättre utvecklad. Anledningen till att jag fastnade för den var dock för att den visades med exakt samma bilstereo som jag har. Hade det bara varit några enklare grejor att ändra på i programmet så hade jag kunnat testa redan ikväll...

Nu verkar det som om (om det nu är korrekt disassemblerat så det inte är data i detta området) man använder komparator 2 istället för 1 som inte används alls (16F628A har bara en) och även kör BCF och BSF på PORTE av någon anledning, fast ingenting är inkopplat där.

Så jag antar att man kanske skulle göra det enkelt för sig och beställa en 16F877A, testa med PicBASIC Pro versionen medan man väntar och sedan gå vidare om det inte funkar.

Vad har du för stereo i SAABen då?
Det är väl bara att ta en kväll med google och leta.
Jag hittade denna:
http://82.182.142.23/saabradio/index.htm

Annars låter det kanske bättre att koppla in sig på telefon-ingången där den delas upp till stereo och haka på en kabel där.
http://www.mitt-eget.com/saab/faq_audio.shtml

Här fanns ett exempel:
http://jurgar.wordpress.com/2008/07/10/ ... -audio-en/
http://gatoalfa.calipso.com.co/radioMod ... od-AHS.pdf
Verkar inte som man kan ställa bas och diskant när man använder telefoningången, så då är väl kassettexemplet bättre - om man sluppit peta i en kassett.

Verkar som om det är besvärligt med CD-växlar ingången, om det ens finns?

Fast 16F887A finns ju i mindre kapslingar också om man vill. dels ytmonterat men även PLCC.

I saaben har jag en AS1, alltså radio+CD+CDväxlarstyrning.. vore nice om man kunde jacka ins ej på den med en MP3-spelare så att man kopplade in sej på linein, och kunde växla låt med knapparna på ratten.

I din första länk där moddar dom ju om så att bandaren (i AS2-stereon) istället används som linein.. nu har jag ingen bandare, men även om jag hade haft det så hade det känns lite B att göra så, plus att det bara blir linein och inte nån styrning.

Jo, det är ju iofs sant, då är del väl mest oviljan att handla som sätter stopp.
Men är det PDIP så underlättar det, bara att peta i experimentplattan vid test och sen i prototypkortet.

Men jag testar väl den versionen som var gjord för 16F628A så får detta vila så länge.

Aha, då låter det som om det blir komplicerat.

Vill du bara ha linje in så kunde man anslutit en 3,5mm kontakt med brytare och kopplat in sig på ljudkablarna från CD-växlaren, men det blir ju ingen styrning då förstås. Det är väl inget annat att göra än att googla eller göra allt grovarbete själv med att avlyssna bussen osv.

Bara för sakens skull är här PicBASIC Pro programmet som jag OCR:at och skrivit rent från hittad pdf.

'  Description:
'  		This Pic Basic/assembly code allows for communication
'  		between the head unit and the Atmel. Using the PICl6F628
'  		to interpret the protocol this code allows the necessary

'  Comments:
'  		When debugging with Serout2 you the pause statements at
'  		the beginning of each GoSub packet routine needs to be
'  		changed. Make them shorter.
